They only asked for previous passports, PR card and COPR, and two IDs. I have however brought many other documents with me including university transcripts, proof of employment, utility bills and leases. During the interview, I was asked about my employment during my stay in Canada so I presented the proof of employment to the agent who examined it and add it to my file. Apart from that, he did not ask for any other document but I think being prepared is better than getting any request for more documents after the interview.
Thank you Suin, two week windows seems a bit optimistic for me, but hope is always good
